Post replays where you do stuff a lot longer, I work with the biggest files first because they often have the most detailed spars and parkours, because file size goes up the more joints you use and change through out the replay.
The people you see the most on my channel do just that and that's why they get in so often. Make a epic spar collab or self spar and you can get in the next video quite easily. It takes time and effort but guarantees entry, so it pays off.
Good luck
